A:Currently, a number of herbs are being promoted for multiple uses. Reishi mushroom is one such panacea, and it is claimed that it is effective for many of the conditions for which ginseng is used. At present there is insufficient proof that ginseng has properties other than those of other tonics , and thus its properties need to be studied more by science to see how effective it really is. The same considerations apply to many herbs and alternative medicines, including reishi. The user of such products should recognize that any benefit is unlikely to be more noticeable than the effect of a reliable multivitamin product and the latter is usually far less expensive.
